Sleeping in the lateral, or side position, as compared to sleeping on one’s back or stomach, may more effectively remove brain waste, and could reduce the chances of developing Alzheimer’s, Parkinson’s and other neurological diseases, according to researchers at Stony Brook University.
The U.S. Defense Department recently began testing a laser that might someday be affixed to drones to knock incoming missiles out of the sky.
Marine Corps Gen. Joseph Dunford, nominated by the Obama administration to replace Army Gen. Martin Dempsey as chairman of the Joint Chiefs of Staff, said he agrees with Navy Adm. William Gortney, head of U.S. Northern Command, on the need for the military to develop ways to thwart ballistic missiles earlier in flight, possibly with lasers.
Researchers funded by the National Institute of Biomedical Imaging and Bioengineering have designed a nanoparticle transport system for gene delivery that destroys deadly brain gliomas in a rat model, significantly extending the lives of the treated animals. The nanoparticles are filled with genes for an enzyme that converts a prodrug called ganciclovir into a potent destroyer of the glioma cells.
Watch your language. Words mean different things to different people – so the brainwaves they provoke could be a way to identify you.
Blair Armstrong of the Basque Center on Cognition, Brain, and Language in Spain and his team recorded the brain signals of 45 volunteers as they read a list of 75 acronyms – such as FBI or DVD – then used computer programs to spot differences between individuals. The participants' responses varied enough that the programs could identify the volunteers with about 94 per cent accuracy when the experiment was repeated.
When you start talking about cosmic measurements, most people have a hard time truly comprehending the figures involved. They become abstract, conceptual -- so much larger than any human experience.
So the age of the universe just seems like a number, but it's a very big number: roughly 13.8 billion years. That means the "edge" of the universe is 13.8 billion light-years away -- so far away that we've never been able to observe it.
